Medicare pays $335.68 for 74185 nationally in the office. Local office rates run $294.91–$459.99.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 74185 covers

74185 represents magnetic resonance angiography focused on blood vessels in the abdomen. Radiologists commonly interpret these studies when clinicians need to assess vessels such as the renal arteries, abdominal aorta, or mesenteric arteries, including concerns such as narrowing or aneurysm. The study may use contrast or be performed without it. It is distinct from a routine abdominal MRI, which evaluates abdominal organs and tissues rather than providing a dedicated angiographic assessment. These studies are performed in hospital or outpatient imaging settings.

Report the code for the abdominal MRA service, and document the clinical indication, imaged anatomy, whether contrast was used, and the interpretation. CMS payment is restricted to specific circumstances, so the service is paid only when applicable coverage requirements are met. The global service includes technical performance and interpretation when billed without a component modifier. Modifier 26 identifies the professional interpretation; modifier TC identifies the technical service, including equipment and staff. When multiple diagnostic imaging procedures are performed, the CMS multiple-procedure reduction applies to both components.
